Outline of Final Research Achievements

This study focused on the visual trait of "separation difficulty" or "crowding" and aimed to determine its effect on reading speed and visual cognitive skills by comparing children with low birth weight (LBW) and non-LBW. The results showed that the LBW group was worse than the non-LBW group in crowding target, even though both groups performed well in single target. These differences were thought to affect the reading speed and visual cognitive skills such as figure-ground discrimination, but the results were not significant in this time. The fact that we could not gather as many subjects as we would have liked due to the coronal disaster may have been one of the factors.Further discussion is needed.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、低出生体重児は読み分け困難の影響をより受けるということがわかった。この結果は、この群における第一選択となる支援アプローチは、音韻障がいを主体とする発達性ディスレクシアの支援アプローチとは異なり、余白や行間を広く取るといった視覚的な環境調整が著効することを示唆する。評価が支援に直結する学習障害の対応法のひとつとしてその意義は大きい。
